 Device for sorting two-dimensional data array / 2279122Device contains matrix of unary first memory registers and matrix of unary registers of second memory, which are identical to each other. Between them a commutator is positioned. Unary memory registers, positioned conditionally in one row, are connected between each other as shifting row registers. Commutator on basis of law given externally connects output of shifting register of first memory, corresponding to i-numbered row, to input of shifting register of second memory, corresponding to j-numbered row in second memory. After sending a packet of shifting pulses to shifting input of i-numbered shifting register of first memory, information from it moves to j-numbered shifting register of second memory. Therefore, transfer of i-numbered row to j-numbered position in new array occurs. Transfer of rows can be realized row-wise, or simultaneously for all, while structure of commutator is different for different cases. |
